Features & Product Details

RallySport Direct is proud to carry pioneering performance products brought to you by Greddy. 

Here, you are looking at the Greddy FV Blow Off Valve, This is a great blow-off valve designed to produce quicker valve response with increased valve travel with improved resistance to premature valve lift and boost leaks. 


  • FV stands for "Floating Valve"
  • Improved valve response
  • Improved resistance to premature valve lift and boost leaks
  • Increased valve travel
  • Unique floating valve design incorporates a revised adjustable dual spring system and diaphragm and valve ratio

    Performs well, five minute install on my 2.5L LeBaron 1 year ago
    5out of 5stars

    After running a cheap bov for almost a year, I was having issues with chopping at partial throttle, boost leak under WOT, and surging on throttle body close. Decided it was time to bite the bullet and upgrade to a name brand unit for the sake of my turbo. I already had the piping and proper flange for a Greddy valve so I opted for the Type FV. I am happy as a clam. Very high quality billet aluminum design, and I love the floating valve setup. It engages flawlessly and was simple to dial in. Needless to say my turbo no longer chops, leaks boost, or surges when I let-off the throttle. The sound is crisp and satisfying. Shipping options were CHEAP and the unit shipped the same day. Bravo RallySportDirect, you guys are top-notch!
